Need HELP! Pinnacle Plumbing

[bethcb]

We need some advice! Just purchased a Pinnacle 36FBTS 4 days ago. There is only 1 gray water lever to empty our tank. There are 2 black water levers. The control panel inside has a Gray 1 and Gray 2. Gray 1 indicates its empty, and Gray 2 indicates its full. During our walk thru I asked if there was 1 or 2 grey and we were told it had 1 tank. Our water is now backing up into our kitchen sink and have no idea on how to empty the water from the kitchen. There's no problem in the bathroom.
Its now Saturday night and we cannot get anyone to even look at this until Monday. Any help or ideas will be appreciated!

We have a Premiere with 2 grey water valves and one black water. Although I am not familiar with your model, I'm wondering if one of the black water valves is mislabelled and is actually a grey water valve.

The other gray water valve is under the trailer and not in with the others. If you look under the trailer you should see it. Close to the front end of the kitchen slide.

We opened both black water levers and they just empty the black water. It is not emptying the 2nd tank. We just spoke to someone at Coach Net and they said there are 2 grey water tanks, 37 gallons each and that there must be a 2nd lever somewhere for that tank. We just don't know where it would be.

Jayflower-You saved the day!!! You are right and we found the lever. We had no idea of its existence and this confirms our previous discussions that the person who did our walk thru in Indiana did not know much about this Pinnacle. Thank you sooooooo much!!!

No worries. I had the same experience 2 weeks ago. Good luck!!

Just curious, Grey 1 is for the kitchen and maybe 1/2 bath and grey 2 is for the masterbath??

[bethcb]

We assume that the grey 1 is for both bathrooms and washer/dryer. Grey 2 is for the kitchen.

jayfowler, thank you, thank you, thank you, so much. Just read your post due to having same problem. Was told lever underneath was to open up main line to drain all tanks! Guy that told me that didn’t know much! Thanks again!

This is a common problem with new owners and new rigs. Best thing is to start out with all tanks drained. Add some water to the kitchen drain, then pull the small valves one at a time until the water drains. Only need a couple of gallons to test.

I marked mine Kitchen and shower to eliminate any confusion. Black is mostly clearly marked but it won't do hurt to confirm them all.

We did the same after we got our new Pinnacle, but ours has 3 Grey tanks, 1 for the kitchen, 1 for the shower and 1 for the washer (which we don't have) maybe one day.....

Yep, ours is pre-plumbed but has no separate tank. We found ours is plumbed to the bathroom tank. Good to know if we ever need it!

Nothing new here....happens far too many times

Same happened to me. I thought second bath sink gray was also kitchen since it is on the same level. Found out when shower backed up that was not the case and water backed up to that sink. Now I always lv both gray valves open and place a small log under drain hose to make a trap to keep
Out sewer fumes.

I have a 2023 pinnacle 36FBTS I have 2 black valves and one gray valve but the display says I have 2 black and 2 gray valves I can’t find the the other gray valve, where is it as it says it’s full ?

Found this on Youtube, looks like it is underneath the trailer just in front of the kitchen slide (around the 6:05 minute mark)

Look under trailer by the front tire driver side

It is right before the dump hook up underneath. That one goes to the kitchen sink. The other gray does shower and all three bath sinks.
